Fetching List public VM Images in Google Cloud

I am using C# Google SDK to fetch the list of public ubuntu or debian VM Images available in Google Cloud. The response is a long list of VM' having primarily the deprecated State as "OBSOLETE".

When applying the filter for ACTIVE state the response is null , Can anyone help on how to fetch the active images, or if the result returned without filter is correct.

Scenario 1 . When no filter is applied

var lstRequest = new ImagesResource.ListRequest(_computeClient, ""); var images = lstRequest.Execute();

Sample Response

============================================================

Scenario 2: On applying filters

var lstRequest = new ImagesResource.ListRequest(_computeClient, "ubuntu-os-cloud"); lstRequest.Filter = "deprecated.state=ACTIVE"; var images = lstRequest.Execute();

Response

Null

I am using Google.Apis.Compute.v1 namespace

Update: As Sam pointed out ACTIVE is a valid state (link) but it's unused in the example list, hence the null result.

I think because the value ACTIVE is invalid.

gcloud compute images list \
--project=${PROJECT} \
--show-deprecated \
--format="value(deprecated.state)" \
| sort \
| uniq

DEPRECATED
OBSOLETE

I got results with neither then either of:

request.Filter="deprecated.state=\"DEPRECATED\"";
request.Filter="deprecated.state=\"OBSOLETE\"";

NOTE Image Projects are not the same as GCP Projects

Compute Engine API v1 only surfaces the Image Project as part of an image's selfLink

When you computeService.Images.List(project);

The value of project should be your GCP project not ubuntu-os-cloud.

Using ubuntu-os-cloud works but it does not filter the results by the ubuntu-os-cloud Image Project.

Also, APIs Explorer is an excellent mechanism to test Google API service calls to ensure you're getting them correct, e.g.:

https://cloud.google.com/compute/docs/reference/rest/v1/images/list?apix=true&apix_params=%7B%22project%22%3A%22ubuntu-os-cloud%22%2C%22filter%22%3A%22deprecated.state%3DOBSOLETE%22%7D
